Patented Aug. 27, 1935 arten srar errar Fries The present inventionrelates in general to applicators or swabs, and more particularly to anapplicator or swab for applying wax to iloors and the like.

The invention has as its main object the pro- Vision of an applicator ofthe above type which shall be light, sturdy, simple in construction andcheap to manufacture.

The main object of the invention is attained in general by providing alight backing or holding member of wood or the like with a novelone-piece clamp member for clamping the pad material to the holder in asimple and eiective manner, the clamp being capable of manufacture froma single small piece of stock sheet metal, such as scrap metal, soformed as to give maximum strength and lightness with simplicity ofstructure.

Other objects and advantages of the invention will be apparent from aperusal of the following specication and the drawing accompanying same.

Fig. 5 is an enlarged fragmentary section on the line 5-5 of Fig. 2.

Referring to the drawing in detail, I is the back or holder, preferablyof wood, having a fiat rectangular base portion 2, and a pair of bores 3and li extending through from the base to the top of the holder,substantially at right angles to the base. The applicator pad 5 issecurely held in place on the base by a substantially ilat sheet metalclamp member 6 held firmly in clamping relation with the holder i byup-standing lugs 'i and 8 which extend up into the bores 3 and 0.respectively, resting against one side of the bore and held securely inplace by screws 9 and I0 wedged down into the bore between the side oithe bore and the lug. The threads of the screws 9 and iti are hardenedso as to cut into the sheet metal lugs 'i and respectively, as indicatedin Fig. 5, where it will be seen that the screw ill is wedged into thebore 4 so as to force the lug 8 against one side of the bore, the screwthreads cutting into both the lug 8 and the opposite wall of the bore.

The clamp member S is stamped from a single piece of sheet metal to forman oblong rectangular metal plate having 4 oblong openings il, i2, I3and it near each corner, so spaced and arranged as to form an oblongframe Withintegral cross arms i5 and i6 extending through the centerfrom side to side and end to end respectively.

The cross arms thus serve to brace the frame, which bracing effect isenhanced by having the arms increase in width toward their junction withthe margin of the frame, as clearly shown in Fig. 4. Serrated clampingedges il are struck up along the outer edges of each of the openings H,i2, etc., substantially parallel to the adjacent one of said edges i8 ofthe clamping me1n- 10 ber and spaced inwardly therefrom as shown inFigs. 3 and 4. Serrated clamping edges i9 are also struck up along theend edges 2B of the clamp. The holding lugs 'i and 8 are also integraland are struck up from the body material of the 1. cross arm it and soformed as to project upwardly, each from a point on the longitudinalaxis of the plate on opposite sides of the center of the plate, butcloser to the adjacent end of the plate than to the center. Thisarrangement posi- 20 tions the lugs midway between a pair of opposedparallel clamping edges il', but offset longitudinally toward anadjacent clamping edge i9, thus eiecting a substantially evendistribution of pressure along the serrated clamping edges when the lugsare secured in clamping relation with the holder i.

It will be clear from Fig. 4 that the cutting out of the holes ii, i2,etc., materially lightens the plate without weakening it as a rigidclamp, due to the fact that the side and end margins of the clamp framethus formed are reinforced midway by the widening junction between thecross arms and the margin of the frame, the frame being furtherreinforced by the struck up clamping edges il and i9. The clamp 6 is ofgreater Width than the base portion .'12 of the holder so as to projectboth sides thereof, while the serrated clamping edges il are spaced insumciently to underlie the base 2, so that the 40 door pad 5 will besecurely clamped between clamp 6 and base 2 and at the same time extendwell out in advance of the side edges of the base and holder, as shownin Figs. 1 and 3. This extension of the pad will then act as a buffer toprevent marring of side trim or wash boards.

As shown in Fig. 2 the clamp isumade slightly shorter than the base ofthe holder so as t0 underlie the ends of the holder permitting theclamping edges i9 to clamp the ends of the pad 50 against the base.

In applying the pad to the holder it is first wrapped around the clamp 6as indicated in Fig.

3 and the clamp placed in position as shown, with the holding lugsextending into the bores in the holder and resting against one side ofthe bore. The holder I is now pressed down rmly on to the clamp so as toclamp the upper lappedover portions of the pad nrmly between the clampand the holder while the screws 9 and i@ are placed in position andscrewed down into the boresy between the side of the bore and the lug,the hardened threads of the Screw cutting grooves in the lug to hold theparts in this clamped position, after which the downward pressure on theholder may be released. .Y

After the parts are thus assembled with the padheld rmly between theclamp and holder, the clamp may be further tightened by further turningthe screws after their heads have engaged with the top of the holder,which will cause the lugs to be drawn up by coaction of the screw threadwith the grooves out in the lugs.

While I have herein shown and described av What I claim is:

1. A sheet metal clamp for applicator comprising a main body of sheetmetal having a perimeter substantially smooth in edges, and pad bitingserratons integral with Said body projected at right angles from theupper side of said body, marginally inwardly removed from said substantially smooth edges.

2. An applicator comprising a base and a coacting pad clamp, the lattercomprised of sheet metal having a perimeter of substantially unbrokenlines, pad biting serrations integral with said clamp and projected atright angles from the upper surface thereof, Within the perimeter of theclamp and within the perimeter of the base, whereby they bite down onthe pad between the clamp and the base, and the pad may be foldedsmoothly around the unbroken clamp perimeter, and also a pair ofintegral tongues of sheet metal projected at right angles from the uppersurface of said clamp and entering the body of said base whereby tosecure the clamp to the base.
